Ministry of Transportation and Infrastructur Suit Woolridg Strt Coquitlam, BC V3K 0B8 SUPPLEMENTAL GEOTECHNICAL LABORATORY TESTING GEORGE MASSEY TUNNEL REPLACEMENT PROJECT, RICHMOND & DELTA, BC Dar Ms. Kong, As rqustd by th Ministry of Transportation and Infrastructur (MoTI), in mail corrspondnc datd April 28 and May 2, 14, w ar plasd to provid th rsults of supplmntal laboratory tsting carrid out on sampls collctd during Goldr s gotchnical invstigation, btwn Novmbr 13 and January 14, as part of th Gorg Massy Tunnl Rplacmnt Projct. Dtails of th gotchnical invstigation ar prsntd in Goldr s factual rport, datd April 24, 14. Supplmntal Attrbrg limit (ASTM D ), watr contnt (ASTM D ), and on-dimnsional consolidation (ASTM D2435/D2435M-11, Mthod A) tsting hav bn prformd on fiv rlativly undisturbd 76 mm piston tub and 64 mm Shlby tub sampls, slctd by MoTI. At th rqust of MoTI, th on-dimnsional consolidation tst load schdul was modifid from standard procdur to includ an unload-rload cycl at a maximum load of 00 kpa. This lttr is limitd to prsntation of th attachd laboratory tsting data, and Goldr has providd no gotchnical intrprtation of th rsults. Soil classification prsntd on th consolidation tst rsults is basd on visual dscription and plasticity tsting only, and no additional particl siz analysis of th soils has bn prformd. Should you hav any qustions or commnts, plas do not hsitat to contact th undrsignd. Yours vry truly, GOLDER ASSOCIATES LTD.
